(2) Enter adjustment mode [05]. Change the value for code [434] to adjust the bottom margin.
* This adjustment will have an effect only on the image printed on the back of the paper (printed side
delivered facing downwards) in duplex copying. Remember that it will not affect the image printed in
simplex copying, the one printed on the front of the paper (printed side delivered facing upwards) in
duplex copying, and the print image quality.
* In duplex copying, the bottom margin on the back of the paper may be narrower than on the front in
simplex or duplex copying, depending on the paper size and how much paper is moistened. This results in
the faint image at the trailing edge on the back of the paper. Adjust the bottom margin, in order to clearly
copy at the trailing edge on the back of the paper.
• Use steps (a) to (b) to adjust the bottom margin.
(a) With the platen cover or RADF opened, make a double-sided copy. (Copy a solid black image.)
• Checking the copy image, determine how much the bottom margin should be increased.
* Select the best paper size for duplex copying, if necessary. It is recommended to use the paper, which
is most frequently used for duplex copying.
* When making a double-sided copy of the solid black image, place blank paper on the original glass,
allowing the solid black image to be copied only at the trailing edge on the back of the paper, for toner
saving purposes.
(b) Enter adjustment mode [05]. Change the value for subcode "0" of code [434] to adjust the bottom
margin on the back of the paper.
• The amount of change per step varies, depending on the paper size.
• Long size (A3/B4/LD/LG): The bottom margin will be increased by 0.042 mm per step.
• Short size (A4/LT): The bottom margin will be increased by 0.028 mm per step.
• Middle size (A4-R/LT-R, etc.): The bottom margin determined for the short size will be applied.

* Set the value in increments of approximately 12, while checking the copy image until the optimum value is obtained.
* Set "0" for the subcode. Setting "1" for the subcode allows you to adjust the right margin on the back
in duplex copying, but it is not necessary here. Therefore, never change the value for subcode 1.
• After the adjustment, make a double-sided copy again, with the platen cover or RADF opened and
check the image at the trailing edge on the back of the paper. If further image quality adjustments are
still necessary, repeat step (b).
<Hint> If the user is concerned regarding the image quality at the trailing edge on the back of the paper,
set a slightly wider bottom margin (3 to 4 mm). If not, it is recommended to set it to 2 to 3 mm.
